Automatic spraying system for pipe fitting bell and spigot

Abstract

The invention relates to an automatic spraying system for a pipe fitting bell and spigot, which comprises a first robot used for spraying the inner wall and the end face of a pipe fitting bell mouth,a rotary supporting device used for driving the pipe fitting to rotate, a lifting device used for lifting the pipe fitting, a second robot used for spraying the outer wall of a pipe fitting spigot anda pipe diameter detection device used for detecting pipe diameter information of the pipe fitting. The first robot sprays the inner wall and the end face of the pipe fitting bell mouth according to bell mouth spraying track parameters corresponding to the pipe diameter information; and the second robot sprays the outer wall of the pipe fitting socket according to the socket spraying track parameter corresponding to the pipe diameter information. Automatic spraying operation can be conducted on the inner walls of bell mouths and the outer walls of spigots of pipe fittings with different pipe diameters, automatic mixed production operation of the pipe fittings with different pipe diameters can be achieved, and the problems that a manual supplementary brushing mode needs to be adopted for bell and spigot pipe fittings on a production line, the labor intensity is high, the operation environment is poor, and the product consistency is poor are solved.

Description

technical field [0001] The invention relates to the field of anti-corrosion coating of pipe fittings, in particular to an automatic spraying system for sockets of pipe fittings, which can realize the automatic spraying operation on the inner and outer walls of the sockets of pipe fittings. Background technique [0002] At present, in the production process of pipe fittings, in order to meet the needs of anti-corrosion, it is sometimes necessary to spray asphalt on the inner wall of the socket and the outer wall of the socket of the pipe fittings, such as ductile iron pipes or steel pipes. Most of the asphalt spraying still adopts manual brushing method, which has high labor intensity and poor working environment. Although special machines are also used for spraying, it is impossible to achieve precise spraying of cast pipe sockets. The spraying effect at the lap joints between the inner wall of the socket and the cement lining and the small groove of the socket cannot meet t...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of inconvenient spraying on the production line of pipe fittings that need to be sprayed at present. The types of pipes include cast pipes, steel pipes or other pipe fittings that need to be sprayed with sockets. Manual repainting is used, which has problems such as high labor intensity, poor working environment and poor product consistency. An automatic spraying system for pipe fitting sockets is provided to realize automatic spraying of the inner and outer walls of pipe fitting sockets.
